The present inventionrelates to a weather strip and sash balance incombination, and more particularly to a weather strip used incombination with a novel attachment means adapted to be used withvarious novel adjustment means for adjusting the length of a tensionspring used therein, for the easy lowering and rais ng of a window sashand holding the sash in any positron of adjustment.

Heretofore, combination weather strips and sash balances have been ofthe construction which proved to be relatively expensive in cost,difficult to mount with respect to the window sash and frame, andarduous in connection with adjusting the spring tension with respect tothe various weights and sizes of window sashes. It was found necessaryto remove the entire Weather strip, removing, as a result, the sash aswell, before the necessary adjustment could be made on the spring in thesash balance in order to obtain the perfect balance desired. Not onlythe element involved, but also the labor and cost, afiorded various andnumerous problems.

It is an object of the present invention to provide a window sashbalance having a weather strip which is easily mounted and servesyieldingly to hold the window sash in a weather-tight connection withrespect to the window casing.

Another object of this novel device is the provision of a weather stripconstruction for window casings having a slidably mounted sash balancewherein means for counterbalancing the sash are easily installed, andeasily adjustable to counterbalance sashes of various weights and sizes,using the means provided for adjusting the spring member according toneed or desire.

A further object of this invention is to provide a weather strip havingguideways wherein the sash balance is installed, which eliminatecatching or snagging of the spring member and provides a smootheroperation of the sash balance with respect to raising and lowering thewindow sash.

Another advantage of this novel invention is the provision of a sashbalance bracket which is easily installed in the window sash, which maybe easily removed and replaced when adjustments are needed in the springmember of the sash balance, and which also p-ivotally holds theadjustment means received in the novel weather strip.

Another important object of this combination weather strip and sashbalance is the provision of various novel adjustment means which may beemployed in connection with a novel sash balance bracket providing easyaccess to the spring member so that the necessary adjustment may be madewithout disengaging the entire sash balance from its operative positionwith respect to the mounted weather strip. These adjustment means arerelatively inexpensive, yet provide excellent service.

Other objects, advantages and variations of the present invention willbecome more apparent from the following detailed description, taken inconjunction with the accompanying drawings showing the variousembodiments of the invention.

In accordance with the present invention, a weather strip and adjustablesash balance in combination, for the sliding sashes of window casings,comprise a weather strip formed from aluminum, or other such suitable3,021,578 Patented Feb. 20, 1962 ice material, having track portions forthe receiving of the sides of the sashes, a parting strip, housingchannels, tracks, means for securing the top portion of the weatherstrip, along with the adjustable spring member of the sash balance tothe jamb of the window casing, a novel sash balance bracket easilyattached and detached from the bottom of the sash, and variousadjustment means for adjusting the tension of the spring member of thesash balance according to need without removing the entire weather stripand sash balance from their operative position with respect to thewindow sash and frame. The weather strip, which retains the sash balancein an operative position with respect to the sashes, is bow-formed,assuring a weather-tight sealing of the sashes, and also provides trackswhich not only enclose the spring member of the balance, but alsoprovide a bathe-like obstruction to the pas-sage of air around the sash.The novel sash balance and adjustment means hold the slidably mountedsashes in any position, in an upward or down ward movement,

Preferred embodiments of the present invention are illustrated in theaccompanying drawings, in which:

FIGURE 11 is a side view of the embodiment of FIG- URE 10.

Referring now to the drawings, and in particular to FIGURE 1, thevertically extending weather strip, which is indicated as a whole by thereference character 30, is mounted on the jamb 5 or pulley stile of thewindow frame, at the top portion, as will be more fully explained. Thewindow sashes 7 are of a conventional construction and consist of anouter sash and an inner sash, having grooves 38 located in the sides ofthe sash members 7. The weather strip 30 comprises an elongated bodyformed from aluminum, or other such suitable material, having Theparting strip 34 and the track portions 32 and 33 v are so shaped as toexert pressure against the sashes 7,

slidably mounted therein between the parting strip 34 and the inwardlybent flanges 31, and to assure a free lateral movement of the sashes 7in such a way so as to prevent any rattling or binding of the sashes 7placed therein.

As clearly illustrated in FIGURE 1, the curvature imparted to the trackportions 32 and 33, the sides of the parting strip 34, forming the innerwalls of the track portions 32 and 33, and designated by the referencecharacter 60, and the side walls 61, engages the edges of the sash 7 andrenders the weather strip 39 normally in a bow-like form in crosssection so that when the same is secured in position to the jamb 5, thesash 7 is held securely and weather-tight with respect to the jamb bythe manner of spring-like tension due to the yielding pressure exertedon the sashes 7 by the form of the Weather strip 30.

A U-shaped housing channel 35, running vertically in the center of thetrack portions 32 and 33 for a portion of the length of the portions 32and 33, is formed from the body with a chamber 36 to receive the spring21. This U-shaped channel extends outwardly into the groove 33 of thesash 7, the distance from the top of the jamb 5 to a portion of thetrack portions 32 and 33. At this point on the weather strip 39, wherethe housing channel 35 ends, a raised flange arrangement formed from thebody, forms vertical tracks 37, running the remaining distance of thelength of the weather strip 30,

t to the bottom, so that the spring 21, when fully extended,

may ride in the vertical guideway formed by the housing channel 35 andthe last-named tracks 37. The guideway,

comprising the housing channel 35 and the tracks 37' also provides abattle-like obstruction for the exclusion of the passage of air aroundthe sash 7.

Located at the top portion of the housing channel 35, about one-fourthof an inch from the top edge, is a screw hole 42 located in an eyelet76, which receives a drive screw 41. In this manner, the Weather strip30 is secured to the jamb 5 at the top of the window casing, and floatsat the bottom, thus forming a tight seal with the sash 7. The drivescrew 41 also anchors the spring 21 by means of a loop 22, through whichthe drive screw 4-1 is inserted.

The sash balance, as illustrated in FIGURE 1, and represented by thereference character 8, as a whole, comprises a spring 21 having a loop22 located at the top edge where it is held in an operative positionwith respect to the jam-b 5 by means of the screw 41, a loop 23 locatedat the bottom end of the spring 21, an adjustment rod 24 having a seriesof curved teeth 25 adapted to receive the loop 23 and lock the spring 21in position, and a sash balance bracket 29, means for attaching the sashbalance 8 in position with respect to the sash 7, having the adjustingrod 24 pivotally mounted thereto by means of a semi-tubular rivet 27, orother such suitable means such as an eyelet or pin, entered through anopening 26 in the plate 1 of the sash balance bracket 29 and through theadjusting rod 24.

As clearly illustrated in FIGURES 2 and 3, the sash balance bracket,represented as a whole by the reference character 29, has sharp toothedprojections 2 located on either side of the cash balance bracket 29, andadapted to be inserted in the bottom of the sash 7 to secure the sashbalance 8 with respect to the sash 7. It is to be understood that theprojections 2 of the sash balance bracket 29 are not essential to theapplication of the sash balance bracket 29 to the sash 7. The tension ofthe spring 21, in combination with the extending arm of the sash balancebracket 29 will hold the bracket 29 in place on the sash 7, such thatthe spring adjustment is maintained.

The projections 2 have been added in design to offset any potential sideshift of the sash balance bracket 29 and possible contact with theweather strip 30. The plate 1 is formed from the body of the sashbalance bracket 29 and extends vertically upward into position withaccordance to the tracks 37 of the weather strip 30. The opening 26 inthe plate 1 is adapted to receive a semi-tubular rivet 27, or other suchsuitable means such as an eyelet,

which pivotally mounts the adjusting rod 24 to the sash balance bracket29. The adjusting rod 24 is held in position with respect to the weatherstrip 30, and more particularly to the tracks 3'7 and the housingchannel 35 Which receive the spring 21 of the sash balance 8.

Assuming that the weather strip 30 and the sash balonce 8 have beenplaced in an operative position, i.e., the weather strip- 33 is placedtangent to the jamb 5 and secured thereto by means of the screw 41 whichalso holds the spring 21 of the sash balance 8 in position, the spring21 is entered into the housing channel 35, extended downward and ridesalong the tracks 37, the adjusting rod 24 is connected to the loop 23and to the sash balance bracket 29, attached to the bottom of the sash 7by means heretofore explained. It is possible to either decrease orincrease the length of the spring 21, and therefore the tension, withoutremoving the entire sash balance 3 from its operative position, by thefollowing simple operation.

The window sash '7 is raised so as to allow the removal of the sashbalance bracket 29 from its secured position held thereto by means ofthe toothed projections 2 entered in the bottom of the sash 7. in thecase where no projections are used on the sash balance bracket 29, thesash balance bracket 29 is pulled downward. When the sash balancebracket 29 has thus been removed, the adjusting rod 24, along with thespring 21 of the sash balance 8 connected thereto, is pulled down alongwith the sash balance bracket 29, so as to allow access to the loop 23which is caught on one of the series of curved teeth 25 on the adjustingrod 24; The loop 23 is then moved to the desired position, either upwardor downward on the adjusting rod 24 and locked in one of the recesses 4formed by the curved teeth 25, so that the spring 21 is secured in itsnew locked position with respect to the adjusting rod 2'4, thusadjusting the tension of the spring 21 in the sash balance 3. Thetension of the spring 21 pulls the adjusting rod 24 along with the sashbalance bracket 29 upward, and the sash balance bracket is replaced inits original position with the projections 2 assuming their initialplace, as does the spring 21 in the housing 35 and the tracks 37. Inthis manner, it is not necessary to remove the entire sash balance 8 andthe Weather strip 3t? from the window casing in order to make any neededadjustments in the spring 21.

From the above detailed description, it is seen that the combinationweather strip 30 and sash balance 8 comloops 71, is pivotally mounted onthe sash balance bracket 29 by means of a semi-tubular rivet 27, orother such suitable means, entered through the plate 1 of the sashbalance bracket 29, thus holding the adjustment wire 70 in position. Thelower end of the spring 21, forming a loop 73 is entered into one of theloops 71 of the adjustment wire '79, thus attaching the spring 21 to theadjustment wire 7%. Instead of the loop 73 located at the bottom end ofthe spring 21, a hooked end (not shown) may be used to secure theposition of the spring 21 to the adjustment wire 70. In this manner, itis possible to adjust the length and therefore the tension of the spring21 of the sash balance 8 by removing the sash balance openers racket 29from its position in the bottom of the sash 7, pulling downward so as toallow access to the looped adjustment wire 7d and spring loop 73, andinserting the spring loop 73 in one of the loops 71, so as to secure theadjusted tension of the spring 21. The looped adjustment wire 79, alongwith the sash balance bracket 29 is pulled up to the original operatingposition, i.e., the spring attached to the adjustment wire 70 returns tothe housing channel 35 and rides along the tracks 37 in the weatherstrip 59 and the sash balance bracket 29 is replaced in its position atthe bottom of the sash 7.

Another variation of the looped adjustment Wire 70 is illustrated inFIGURE 6. This adjustment wire 70 may be used in the same manner asexplained hereinabove, with the exception that the sash balance bracket29 is not used. In this case, a sharp bent end portion 74 of theadjustment wire 70 is inserted into the bottom of the sash 7, thusholding the adjustment wire 70, cooperating with the sash balance 8securely in position. it is not necessary to have a pro-drilled hole inorder to insert the sharp bent end portion 7 4 which may be pushed ordriven into a wooden sash. The pre-torming of the hole or opening toreceive the portion 74, of course, would be necessary-in a sashconstructed of non-yielding material. With the same facility, ashereinabove described, the

adjusted spring 21 may be replaced in its on'ginal operative position,after the adjustment has been made.

FIGURE 7 illustrates yet another modification of an adjustment meansused in combination with the weather strip 36 and sash balance 8, whichmay be used with or without the toothed sash balance bracket 29, asshown in FIGURE 2. In this case, it is held in a relative position tothe sash 7, by ".1 conventional bracket, represented by the referencecharacter 80 placed tangent to the bottom of the sash 7 having anadjusting rod 83. afiixed thereto by means of a pin 82, or other suchsuitable means. This adjusting rod 31 has a fork 86 having a diagonallybent end portion 85 located in the upper portion of the adjusting rod81. The bent end portion 85 of the fork so engages in one of therecesses 84 found between the beads 83 which comprise a conventionalbead-type chain, designated as a whole by the reference character 99.This is further clearly shown in an enlarged view of the arrangement inFIGURE 8. The upper part of the bead-type chain 98 is attached to a loop91 of the spring 21 by means of a chain attachment 87. The upper part ofthe spring 21 is attached to the jamb 5 by means of a screw 41, ashereinbefore explained, entered into the loop 22. In this way, thespring 1 of the sash balance 8 is secured in position. When anadjustment is desired, the bracket 8% is removed from its position withrespect to the bottom of the sash 7, and the adjusting rod 81 is pulleddownward along with the bead-type chain 90. The bent end portion $5 ofthe fork do is then placed in a recess 84- between the beads 83 so thatthe adjustment in the length of the spring 21 is made secure accordingto need, and thus the position of the spring 21 is fixed with respect tothe adjusting rod 31. The spring tension then pulls the spring 21 andthe adjusting rod 81 into the weather strip 3! with the adjusting rod 81and the spring 21 of the sash balance 8 in their positions with respectto the housing channel 35 and the tracks 37. The sash bracket 89 returnsto its original position cooperating with the sash 7. This beadtypechain as and the adjusting rod 81 having a fork 86 located therein, mayalso be used in conjunction with the sash balance bracket 29, aspreviously described, with or without the projections 2, so that theadjusting rod 81 is pivotally mounted thereto.

Still another modification of an adjustment means used for adjusting thespring 21 in a sash balance 8 used in combination with the novelWeatherstrip 30, is illustrated in FIGURE 9. The adjusting rod 24 havinga series of curved teeth 25 adapted to receive a loop 23 in one of therecesses 4 formed by the teeth 25 and to lock the spring 21 in anadjusted position, is pivotally mounted on a conventional bracket bymeans of a pin 82, or other such suitable means. The upper end of thespring 23 of the sash balance 3, forming a loop 22, receives a screw 41entered therein, thus securing the spring 21 to the jamb 5 and holdingthe spring 2-1 in a fixed position with respect to the weather strip 30(not shown). The operation for adjusting the tension of the spring 21 isthe same as hereinbefore explained.

FIGURES 10 and 11 illustrate yet another adjustment means used incombination with the sash balance 8 and the weather strip 30. Theadjustment rod loll comprises a series of vertically spaced serrations101 and a dimple 192 located at the top end of the adjustment rod 100.The adjustment rod 10! pivotally mounted to a standard bracket 80 bymeans of a pin 82, or other such suitable means, may also be used withthe toothed sash balance bracket 29, or other sash balance brackets. Aslotted washer 103 having a slot 194 and an off-set hole 165 is slidablyadapted to lock in one of the series of serrations 101 of the adjustmentrod 100, thus locking the spring 21 of the sash balance 8. This isaccomplished by the hook end 106 of the spring 21 entered in the off-sethole 105, thus by the tension of the spring 21, wedging and locking theslotted washer 103 in position in one of the serrations 101 of theadjustment rod 100. The dimple 102 prevents the slotted washer 163attached to the spring 21 from leaving the adjustment rod 166. When anadjustment is desired with respect to the spring 21. of the sash balance8, the bracket 80 is removed from its posi tion with respect to the sash7 and pulled downward to expose the spring 21 and the slotted washer 103located on the adjustment rod 1%. The slotted washer 103 is grasped andturned so as to place the surface of the adjustment rod 109 at rightangles to the long dimension of the adjustment rod too. The slottedwasher 103 is moved up or down to obtain the desired spring tension, andallowed to cock on the adjustment rod when the desired tension isobtained, thus wedging and locking the slotted Washer H93 in one of theserrations 101, where the tension of the spring 21 will hold itsecurely. The spring 21 pulls the adjustment rod 100 back into itsoriginal position in the weather strip 30 and the bracket 8% is returnedto its initial position with respect to the bottom of the sash 7.

Thus it is seen that the various adjustment means presented hereinabovemay be used with the novel sash balance bracket 29, or with aconventitonal bracket 88, in combination with a sash balance 8 and aweather strip 30, for increasing or decreasing the tension of the spring21 used for raising and lowering a sash 7. It has also been illustratedby description and drawings, that the necessary adjustments may be madein the spring 21 of the sash balance 8 without removing the entireweather strip 30 and the sash balance 8 from their operative positionswith respect to the window casing and sash 7. It is also seen, from theforegoing desecription, that the modifications of the adjustment means,with or without the novel sash balance bracket 29, may be usedseparately for counterbalancing purposes, without a weather strip 30, asabove disclosed.

'It should also be noted that the combination weather strip 30 and sashbalance 8 having adjustment means may be used on one side of the sash 7,while a spiral sash balance is employed on the opposite side of thesash, in combination, for counterbalancing purposes.

It will, of course, be understood, that various changes may be made inthe form, details, proportions and arrangement of the parts, withoutdeparting from the scope of our invention, as set forth in the appendedclaims.
